Figure 4. Performance of nanocrystalline Si nanowire shell solar cells.

Figure 4

(a) Total (specular and diffuse) reflectance of nanocrystalline Si (nc-Si) nanowire (NW) shell solar cells with an average nanowire length l of 525 nm and 800 nm, and a planar nc-Si control device. (b) External quantum efficiency (EQE) spectra of the nanocrystalline Si nanowire shell solar cells. The core-shell solar cell with the longest nanowires (l = 800 nm) demonstrates the highest quantum efficiency at nearly all wavelengths (λ = 300 to 1000 nm). (c) J–V curves under AM 1.5 global illumination (100 mW/cm2) of the nanocrystalline Si nanowire shell solar cells.
